Why book with us in Seaham
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
How much does sheep's wool or natural loft insulation cost in Seaham?
Installing insulation in a home is zero-rated for VAT until 31 March 2027 and 5% after that, under HMRC's rules for energy-saving materials (notice 708/6).

Questions about sheep's wool or natural loft insulation in Seaham
Do you take on jobs outside Seaham?
Yes. We also work in Peterlee and Chester-le-Street and elsewhere in County Durham.
Will I get a written quote for work in Seaham?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How soon can you visit a home in Seaham?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Is sheep's wool insulation worth the extra cost?
In an older breathable house, or if you care about the material, often yes. In a modern semi with plasterboard ceilings the extra cost buys little performance.
Do moths eat sheep's wool insulation?
Insulation-grade sheep's wool is treated against insects. We use products sold for loft insulation, not raw fleece.
